Research workflow and evaluation framework of the thesis (Source: Sara Đurović, MSc thesis, 2026).

The thesis investigates how the quality and research usability of synthetic text generated by large language models can be assessed, using mental health diary entries as a sensitive domain where access to real-world data is limited, and focusing on a multidimensional evaluation framework rather than a single quality metric.

ABSTRACT – This thesis presents a methodological evaluation of the quality and research usability of three synthetic mental health diary datasets produced through workflows based on GPT-5.5, Claude Sonnet 4.6 and Gemini 3.1 Pro. Each dataset contains 1,000 entries across 100 journals, sharing a common data schema and co-generated labels, with the journal treated as the unit of statistical independence. The evaluation combined cluster-aware permutation inference with Benjamini-Hochberg correction, a classifier two-sample test against a human reference corpus (SemEval-2026 Task 2), cross-dataset transfer experiments, a TF-IDF versus RoBERTa comparison, and zero-shot mmBERT transfer between paired English and Montenegrin text. The datasets differed significantly in seven of nine labels, and synthetic text remained clearly separable from human-written text even after controlling for text length (balanced accuracy 0.9855–0.9942). All 30 cross-dataset comparisons showed performance drops (26.04%–84.99%), while RoBERTa outperformed the TF-IDF baseline (macro-F1 0.7872 vs. 0.7118). The findings show that the datasets support controlled experiments but are not distributionally interchangeable, and that synthetic data quality requires multidimensional evaluation rather than a single metric. The results do not establish clinical validity of the labels or rank the generators by quality.

The thesis investigates the application of machine learning, deep learning, and explainable AI techniques to type 2 diabetes risk assessment, focusing on predictive performance, reliability, and interpretability. The research also demonstrates how AI models can support preventive healthcare through accessible, questionnaire-based risk assessment without requiring laboratory measurements.

ABSTRACT – This thesis presents the development and systematic evaluation of machine learning and deep learning models for type 2 diabetes risk assessment using behavioural, clinical, and demographic indicators. The study analysed 253,680 records and compared five models: Logistic Regression, Random Forest, XGBoost, LightGBM, and a deep neural network. Model performance was evaluated in terms of discrimination, probability calibration, and interpretability. While the deep neural network achieved the highest ROC-AUC (0.7728), LightGBM demonstrated the most balanced overall performance. Explainable AI methods, including TreeSHAP, Integrated Gradients, and DeepLIFT SHAP, were applied to identify factors contributing to model predictions. A prototype web application was developed to demonstrate how estimated risks and their explanations could be presented to users.

The results demonstrate the potential of explainable AI for supporting non-invasive risk assessment and preventive screening, while highlighting the importance of model reliability, transparency, and further validation before clinical application.

EuroHPC-Supported Research Advances AI-Based Lecture Transcription for Montenegrin

Results from the Exams 4.0 Proof of Concept project, supported by the Innovation Fund of Montenegro and EuroHPC computing resources, were presented at the international SAMYRAD 2026 conference in Seville, Spain.

The paper “Whisper-Based Lecture Transcription for Montenegrin Higher Education with a Practical Evaluation” was presented at the Smart Algorithms & Models: Your Reach to Advanced Dialogues (SAMYRAD 2026) conference, held on 5–6 October 2026 in Seville, Spain.

Authored by Stevan Čakić, Tomo Popović, Srđan Krčo, and Igor Čulafić, the paper investigates the use of OpenAI Whisper models for automatic transcription of university lectures in Montenegrin, a language not directly supported by Whisper.

The study evaluated three Whisper model variants and three related South Slavic language settings using 30 university lectures covering nearly 38 hours of audio. The experimental work involved generating 4,860 transcripts, with large-scale processing performed on the LUMI EuroHPC supercomputer in Finland.

The results identified Whisper’s turbo variant as the most suitable among the tested models in terms of transcription consistency, evaluated text quality, and processing speed. The research also provided practical recommendations for processing lecture recordings in Montenegrin.

These findings have already been incorporated into a new lecture-transcription module developed within the Exams 4.0 platform, enabling lecturers to transform audio and video recordings into text that can support AI-assisted preparation of educational materials and examination questions.

This R&D effort was conducted as part of the Exams 4.0 Proof of Concept project, implemented by DigitalSmart in collaboration with the University of Donja Gorica and funded by the Innovation Fund of Montenegro.

HPC Montenegro (NCC Montenegro) supported the research team in securing access to EuroHPC computing resources through the EuroHPC JU Development Access programme (project ID: EHPC-DEV-2024D12-018). The computational experiments were performed on LUMI, hosted by CSC in Finland and the LUMI consortium.

This work demonstrates how access to European HPC infrastructure can support applied AI research, foster innovation in higher education, and contribute to the development of digital tools for smaller and underrepresented languages.

AI Research on Premium Domain Name Recommendation Published in IEEE Access

A new scientific paper titled “Premium Domain Name Recommendation via Semantic Retrieval and Reranking of Fixed Aftermarket Inventories” has been published in the international journal IEEE Access. The research was conducted by Milutin Pavićević, Tomo Popović, Srđan Krčo, and Miodrag Vujković from the University of Donja Gorica (UDG) and DunavNET.

The study addresses the challenge of recommending relevant premium domain names from large collections of domains already available for resale. The researchers developed and evaluated an approach combining large language models (LLMs), semantic embeddings, vector search using FAISS, and different reranking strategies. Experiments were conducted on 30,000 domain names sampled from a collection of nearly 700,000 premium domains, with evaluations involving 22 industry experts and 180 students. The results demonstrated the potential of semantic retrieval to improve domain name recommendations while balancing relevance, diversity, and computational cost.

The research also has clear potential for industrial application. Alicorn, a Montenegro-based software company specializing in solutions for the domain name industry, is already developing AI-powered domain name recommendation technologies, including its Name Sentinel platform. The methods investigated in this study could contribute to further improving such solutions, particularly through more effective semantic search and recommendation of premium domains.

The research represents another example of research and innovation supported by European initiatives and connected with the activities of HPC Montenegro (NCC Montenegro), contributing to the development of AI expertise and stronger links between academia and industry.

AI-AGE Research Demonstrates the Potential of Retinal AI for Colorectal Cancer Detection

A new scientific paper developed within the AI-AGE research project, implemented by the University of Donja Gorica (UDG) and the University of Montenegro, has been published in the international journal Current Medical Imaging. The study, titled “Deep Learning Discrimination of Colorectal Cancer using Retinal Fundus Photographs: UK Biobank Case-Control Study,” explores the potential of artificial intelligence (AI) to identify retinal imaging patterns associated with colorectal cancer.

Using 1,600 retinal fundus images from the UK Biobank dataset, the researchers developed a deep learning model based on EfficientNet-B3, achieving an AUROC of 0.945 on an independent participant-level test set. The findings suggest that retinal images may contain valuable information about systemic diseases beyond the eye, opening possibilities for future non-invasive screening and risk assessment approaches. However, further clinical validation is required before such methods can be considered for practical healthcare applications.

The research represents an important achievement for the AI-AGE project and demonstrates the growing potential of advanced AI methods in biomedical research in Montenegro. The project benefits from synergies with HPC Montenegro (NCC Montenegro) and the EuroCC initiatives, which support the development of national competencies in High-Performance Computing (HPC), data analytics, and artificial intelligence. This collaboration contributes to strengthening the research infrastructure and expertise needed for computationally demanding medical AI applications.

The AI-AGE project is implemented by the Faculty for Information Systems and Technologies at UDG and the Faculty of Medicine at the University of Montenegro, with funding from the Ministry of Education, Science and Innovation of Montenegro.
